a bus - ok African buses can have anything on the roof.... from chickens to goats to bikes... and the people crammed inside??? just because there are 70 seats doesn`t mean 150 people can`t fit inside, with a few dangling out the open door and the suspension so bad it SLIDES around the road as opposed to actually being ON the road. Obligatory belches of smoke errupt from the exhaust and banana peels are OFTEN thrown from the windows. ALWAYS wave to the people of the backseat - they will 9/10 times be waving at you already!
